Freshly announced at this week's Consumer Electronics Show in Las Vegas, the PowerWave (iPhone 5 and 5s; $120) combines a swappable, external battery pack that can double your phone's charge, with a convenient case that protects your handset from bumps and scratches—all while adding minimal bulk.

Best of all, the battery pack (and, therefore, your phone) can be recharged wirelessly simply by placing them on top of the provided charging pad.
